Visual Math: Percentages, Ratios, Decimals, and Fractions Poster- Summative Assessment

How many ways can you represent a value? How are percentages, ratios, fractions and decimals related?

o This open-ended, culminating project for a percent unit is a great way for students to stretch their thinking and connect the math concepts they have recently learned.

o It is easily differentiated: assign simpler values (50%, 10%) to students with emerging understanding and more difficult values (12.5%, 66.7%) to students who need a challenge.

o The completed posters make a fabulous bulletin board display or a meaningful piece for student portfolios/parent conferences.

o This product includes 20 different blank poster templates from 1%-100%

Student Instructions:

Each of you will be assigned a percent.

Your task is to represent it in as many ways as possible:

o Equivalent fractions

o Part-to-part & part-to-whole ratios

o Decimals

o Pictures & graphs

o Word problems

o Percent of an hour, a $ amount, a population, or anything you can think of

Grades to Use With:

This project works well in the middle grades (5-8) when these topics are being introduced and linked together.

Standards:

CCSS5.NBT.A.1

Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.

CCSS5.NBT.A.3

Read, write, and compare decimals to thousandths.

CCSS6.RP.A.1

Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”

CCSS6.RP.A.3c

Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.
